Information from man sshd_config:PermitRootLoginSpecifies whether root can login using ssh(1). The argumentmust be “yes”, “without-password”, “forced-commands-only” or“no”. The default is “yes”.If this option is set to “without-password” password authentica-tion is disabled for root. Note that other authentication meth-ods (e.g., keyboard-interactive/PAM) may still allow root tologin using a password.If this option is set to “forced-commands-only” root login withpublic key authentication will be allowed, but only if thecommand option has been specified (which may be useful for tak-ing remote backups even if root login is normally not allowed).All other authentication methods are disabled for root.If this option is set to “no” root is not allowed to login.
